地球是我們所共有的。我們呼吸相同的空氣，喝相同的水，依賴同樣的海洋、森林，以及生物多樣性。經濟學家石井菜緒子的使命是保護這些共有資源，也就是所謂的全球公有物，它們對我們的生存非常重要。在這場讓人開眼界的演說中，談到了地球的健康，石井指出，有四項經濟系統是我們必須要改變的，這麼一來才能守護全球公有物，和地球建立新的社會契約。

保護地球的經濟案例

The fate of shared natural resources like air, water, and forests is at risk as humanity breaches four of nine planetary boundaries. Local traditions once kept resources sustainable, but globalized economies have lost that sense of shared responsibility. With 70 percent of the world’s water used for crops and a third of all food wasted, urgent cooperation is needed. Building new social contracts across cities, energy, consumption, and food systems can restore balance and safeguard the planet for generations.
